Appheation filed March 21, 1917. Serial No. 156,312.-

To all whom it may concern":

Be it known that 1, JAMES W, NANCE, a 1

citizen of the United States, residing at Cincinnati, in the county ofHamilton and and has as its primary object to provide a device of thischaracteradapted'to be'interposed between the intake manifold and'one oftheengine cylinders at the intake port thereinfor heating and breakingup the fuel mixture prlorto its delivery to the engine with thedeviceacting to form'a gasket be-- tween the intake manifold and the cylinderof the engine.

The invention-has as a further object to provide a device of the abovedescribedcharacter having oppositely projecting centering-flanges oneadapted to fit within the intake manifold of the engine and-theother'adapted to fit within the'intake port of the engine cylinder forsupporting'the device in position. I I

And the inventionhas as a still further object to provide a device whichwillbe siniple in constructionand which maybe employed in connectionwith substantially any 'conventional type of internal combustion engine;Other and incidental objects will appear as the description proceeds andin the draw: ings wherein I have illustrated the preferred embodiment ofthe' invention and wherein similarreference characters designateco'rresponding parts throughout the several news Figure 1 is aperspective view partly" Fig. 4 is a sectional view showing a slightmodification ofthe. invention. In carrying out the invention, myimtionopposite to the flange 11 proved device is formed with an annularchannel-shaped body 10' extended to pro- 'vide' an axiallyarrangedlaterally directed centering flange 11. Connected to the body 10 is anannular flange 12 arranged axially of the body to project therefrom inadirec- The flange 12 is of a diameter substantially equal to that oftheflange 11 and Iisprovided at its inner extremity with alaterallydirected annular lip 13 engaging within the annular body 10 forconnecting the flange 12 thereto.

Seated within the body 10 beneath the lip 18 of the flange 12 is acircular screen or :wire' gauze 11 closing the opening through the body.It willthus be observed that in constructing the device, the screen 14may first be arranged within thebody 10 when the lip 13 of the flange12-may thenbe seated against the screen and the channel of the body bentdown to tightly clamp the screen in position as well as to connect theflange 12 with the body. Preferably,- the body 10 and flange 11 areformed of a single piece of'suitable resilient sheet metal so vthatthesides of the channel body 10, will have a corresponding spring action.Also, the flange 12 and lip 13 are preferably formed of a singlepiece ofsuitable resilient sheet metal.v

In order that the construction, operation and mounting of my improveddevicemay be accurately understood I have, in the drawings,illustrated'the invention in connection with a conventional type ofinternal combustion engine 15 having a cylinder 16 provided with anintake port 17. Associated with the engine is the intake manifold 18.The flanges 11 and 12 are each of a diameter to snugly fit within theport 17 of the cylinder 16 or to snugly fit within the intake manifold18 so that, in use, either one or the'other of'said flanges may beengaged within the intake port 17 in the manner shown in Figs. 1 and2.with the other flange engaged within the adjacent end of the'intakemanifold. Whenthus arranged, the body 10 of the device will bedisposed to come between the. cylinder 16 and the terminal edge of theintake manifold and, owing to the resiliency of the body, will provide aspring gasket therebetween with the flanges 11 and 12 acting to centerthe de vice with respect to the intake manifold as well as with respectto the intake port 17.

The device will thus serve to form a tight joint between the intakemanifold and the.

' engine and attention is now directed to the fact that the screen .14will be supported to break up the fuel mixture prior to itsdelivery tothe cylinder. Themesh of the screen 14 is such that the said screen willretain a certain amount of heat and owing to the close proximity of thescreento the'en-.

gine cylinder, the screen will be always maintained heated to thus tend"to heat the fuel mixture upon its passage through the screen.

In. Fig. 4 of the drawings have illustrated a slight modification-of theinvention wherein the body 10' of the device and flanges 11"and 12 areformed as an integral structure with the screen 14:" seated in thechannel of the body. In some instances, a it may be found desirable toconstruct the devicein this manner and it will 'be seen that themodified structure is adapted to be mounted and used in a manner similarto the preferred form of the invention. p

I provide a particularlysimple and efficient construction It willtherefore be seen that for the purpose set forth and a device adaptedfor'use in connection with substantially any conventional type ofinternal combustion engine. V j

Having'thus described the invention, what is claimed as new is;

1. A device of the character described including a body, centeringflanges projecting in opposite directions from the body, and

a screen carried by the body with thebody adapted to provide a gasket.

2. A device of the character described in-.

cluding an annular body, centeringflanges arranged axially of the bodyand extending.

in opposite: directions therefrom, and a screen carried by the body with.the bodyadapted to provide a gasket,

3. A device of the character described-including a body having spacedyieldable sides, centering-flanges extending in opposite directions fromthe body, and a'screen carried by the body with the body adapted toprovide a spring gasket. I

4. A device of the character described including a channel shaped bodyhavinga 1 I, centeringjflange extending therefrom,'.a cen- H teringflange connected tothe body to' ex'-- tend therefrom in a directionopposite to said first'mentioned flange, and ascreen seated in thechannel of the body body adapted to provide a gasket.

5. The combination with an internal com-' I bustion engine having anintake port and an fold and the engine to provide a gasket at the jointbetween the manifold and the, engine. a

In testimony whereof I aflix my signature.
